Subject: [PATCH] ath9k: fix wrong DMA direction in RX tasklet
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit

Commit b5c80475abaad015699384ca64ef8229fdd88758 introduced edma
support for RX, hence bidirectional DMA support. But it
specified the DMA type as DMA_FROM_DEVICE by mistake.
